WaniKani MCP with Claude: Smarter Japanese Study Tracking and Review Planning
The short answer
Claude works with WaniKani through the Model Context Protocol (MCP), a secure standard that lets Claude read and act within the tool. Once connected with an API key, Claude can check study progress, list upcoming reviews, inspect kanji and vocabulary, and update study notes through natural language requests, with permissions the organisation controls.
What is WaniKani?
WaniKani is a spaced-repetition platform for learning Japanese radicals, kanji and vocabulary. It uses structured lessons, scheduled reviews and progress tracking to help learners retain material over the long term. It is used by individual language learners, language schools, corporate training teams and educators who want a structured route into Japanese reading and writing.
How Claude connects to WaniKani through MCP
The Model Context Protocol (MCP) is an open standard that works like a universal adapter between Claude and other software. It lets Claude use a tool securely, reading information and taking actions, with access the organisation approves. For WaniKani, the connection is made using an API key, which identifies the account and defines what Claude is allowed to reach.
Once connected, Claude can typically read study progress, list the reviews due soon, look up the details of specific radicals, kanji and vocabulary, and update study notes when asked. A learner or trainer might simply ask which items are slipping, or request a summary of this week's progress, and Claude retrieves the answer from WaniKani.
Permissions and approvals keep people in charge. Access is limited to what the API key allows, and the consultancy configures the connection with least-privilege settings. Changes such as editing notes can be routed through a confirmation step, and audit logs record what Claude accessed and changed, so the team can review every action.
What you can automate
Weekly progress summaries for trainers
A corporate language trainer asks Claude for a short summary of each learner's progress. Claude reads study data from WaniKani and produces a plain-language report on items learned, reviews completed and areas needing attention, saving the trainer hours of manual checking each week.
Review backlog alerts
A school coordinator asks Claude to list upcoming and overdue reviews across a group of students. Claude highlights where a backlog is building, so teachers can contact learners early before retention drops and study sessions become harder to recover.
Kanji and vocabulary lookups for lesson planning
An educator preparing a class asks Claude to inspect a set of kanji and vocabulary items, including their readings and related words. Claude pulls the details from WaniKani and drafts a lesson outline, reducing preparation time and keeping material aligned with what learners are studying.
Study note maintenance
A learning programme lead wants consistent memory notes across a shared course. Claude can update study notes on specific items when instructed, with a review step before changes go live, so the team keeps mnemonics accurate and up to date without manual edits to each entry.
Onboarding support for new learners
A new employee starting Japanese training asks Claude how to plan their first weeks. Claude checks their current progress and upcoming reviews, then suggests a realistic daily routine they can follow with confidence.
An end-to-end workflow: Corporate Japanese training progress report
TriggerEvery Friday at noon, the learning and development lead starts a report request in the team's workspace.
Claude connects to WaniKani through the API key and retrieves study progress for each enrolled learner.
Claude identifies learners with overdue reviews or stalled progress and ranks them by priority.
Claude drafts a summary of achievements and gaps for each learner, written in plain English.
The summaries are sent to the Microsoft 365 folder used by the training team, with a copy logged in the organisation's ticketing system for follow-up.
The lead reviews the drafts, adds comments and approves them before any learner receives feedback.
OutcomeTrainers spend less time gathering data and more time coaching learners. Follow-up is faster and consistent, and each report is reviewed by a person before it reaches the learner. Results vary by team and programme.
How we set it up
Free automation audit
We review your current Japanese training or study workflows with you and identify where WaniKani data would save time or improve follow-up. There is no cost for this session.
Secure API key connection
We connect Claude to WaniKani using an API key, configured with least-privilege access so Claude reaches only the data your workflow needs. The key is stored securely and can be rotated at any time.
Workflow design
We design the end-to-end process across WaniKani and your other systems, such as Microsoft 365 or your ticketing tool. Approval steps are placed around any action that changes data or affects learners.
Testing and launch
We test the workflow against real past cases, check the outputs for accuracy, and launch with monitoring and audit logs switched on.
Team training
We train your trainers, coordinators and administrators on how to make requests, review outputs and approve actions, so the workflow is owned confidently by your team.

For teams in the US, UK, India and the Middle East
Organisations in the United States and the United Kingdom can align the connection with their state and national data protection requirements. Companies in India must meet the Digital Personal Data Protection Act, 2023, and we design the workflow with its consent and purpose limits in mind. Organisations in the UAE and Saudi Arabia must follow local data protection laws, so we can host Claude in the region that best meets your requirements, including Middle East or India hosting options.

Frequently asked questions
What does the WaniKani MCP server do?
The WaniKani MCP server acts as a secure bridge between Claude and your WaniKani account. It lets Claude read study progress, upcoming reviews and item details, and update study notes when permitted. It works within the access the API key allows, so the organisation decides what Claude can see and change.
Is connecting WaniKani to Claude secure?
The connection is designed for secure, controlled use. It relies on an API key with least-privilege settings, approval steps for changes, and audit logs that record activity. Keys can be rotated or revoked at any time. We also test the setup before launch to confirm it behaves as intended.
What can Claude actually do with WaniKani?
Typically, Claude can check study progress, list upcoming and overdue reviews, inspect radicals, kanji and vocabulary, and update study notes. Users make requests in plain language, such as asking for a weekly progress summary. Consequential changes can be set to require human confirmation first.
How long does setup take?
Timing depends on how complex your workflow is. A simple progress-reporting setup can often be ready within a short period, while a multi-system workflow with several approval steps takes longer. The free automation audit gives you a realistic timeline before any work begins.
Which plan or permissions do I need?
In general, you need an active WaniKani account and an API key generated from that account. The key determines what Claude can access, so we recommend creating a dedicated key for the workflow with only the permissions it needs. Your specific requirements are confirmed during the audit.
